Abstract
Extension personnel serve as vital intermediaries between research institutions and farming communities, and understanding the scientific production surrounding their training, capacity-building, and performance is essential for improving agricultural outcomes. The study applied the PRISMA methodology for a systematic literature review and employed R-studio for bibliometric analysis to examine global research trends on the capacity management of extension personnel, with particular attention to their role in agricultural development and knowledge dissemination. The study examined the literature published between 2020 and 2025. Well-screened data were obtained from the Scopus database with inclusion as well as exclusion criteria results of 65 relevant studies being reviewed. The annual scientific production analysis indicates fluctuating research activity, with a notable peak in 2021 followed by a gradual decline. This suggests that while scholarly interest in extension capacity remains significant, research may be shifting toward more specialized or applied approaches. Citation analysis reveals Ghana and Belgium as the most influential contributors, followed by the United States, South Africa, India, and Nigeria. This distribution highlights both developed and developing countries as key drivers of discourse, reflecting the global recognition of extension services in addressing agricultural and climate challenges. Keyword and thematic analyses further highlight “capacity building,” “adaptation,” and “sustainability” as central concepts, reinforcing the relevance of professional training and institutional support. Overall, the findings demonstrate that strengthening extension personnel capacity is critical to bridging knowledge gaps, enhancing farmer decision-making, and fostering sustainable agricultural development. Future research should emphasize cross-country collaboration, context-specific training, and innovative extension strategies to meet evolving global challenges.
